Description

 The invention relates to a method for selective operator guidance for operator inputs, in particular for operator inputs in a household appliance. The invention further relates to a diaphragm component, in particular for a control panel of a household appliance, and to a method for producing a diaphragm component, in particular for a control panel of a domestic appliance.

 The approaches and refinements described and explained below can advantageously be used in particular in the field of household appliances. Household appliances may in particular be so-called "white goods", that is about conventional devices for cooling, washing, cooking, baking and the like.

 Blende arrangements or control panels in household appliances can usually have interfaces for user interaction. These may be, for example, displays, indicator lights, rotary switches, pushbuttons, pushbuttons, touch-sensitive surfaces or displays, as well as associated labels or symbols. Conventional input elements such as buttons or switches often lead to a certain effort in the production of control panels and aperture arrangements. This effort is the higher, the more possibilities are provided for user interaction, that is, the more user inputs are possible. Furthermore, a significant increase in the number of switches, buttons or the like complicate the operation of the household appliance.

Various approaches are known in the art to enable a plurality of operator inputs on only one "operator interface". For example, the DE 10 2008 032 451 A1 a cooking appliance and a method for operating a cooking appliance, wherein the cooking appliance has an input display, which is designed as a touch screen and can display various information graphically. In particular, it is intended to present information in the form of graphical visualizations and / or animations. However, such a design is associated with a lot of effort and is therefore primarily only for high-end devices and devices for professional use.

 It is therefore an object of the present invention to specify a method for selective operator guidance in a domestic appliance, a diaphragm component suitable for carrying out the method, in particular a control panel for a household appliance, and a corresponding method for producing such a diaphragm component, which can be implemented with little effort and yet allow extended user interaction. In particular, the diaphragm component should be suitable for a large number of variants and configurations in order to be able to limit the manufacturing outlay even with relatively small batch sizes. Furthermore, an operator prompt should be ensured as possible, which facilitates the operation and use of the household appliance. Finally, the aperture arrangement and the household appliance with such a diaphragm arrangement should have a high-quality, integrated design and thus be perceived as optically high quality by the operator as far as possible.

Regarding the operating method, the object of the invention is achieved by a method for selective operator guidance for operator inputs, in particular for operator inputs in a domestic appliance, comprising the following steps:

• Providing a diaphragm component with a sensor layer concealed by a cover layer, in particular a sensor layer which extends in a planar manner and which is designed to detect operator inputs, in particular operator gestures,
• Definition of a current input mode, comprising: assigning at least one defined field to be evaluated for operator inputs, in particular operator gestures, on the sensor layer as a function of the desired input mode, and
• - Acquisition and evaluation of operator input in the field to be evaluated.

 The object of the invention is completely solved in this way.

 Concerning the diaphragm component, the object of the invention is achieved by a diaphragm component, in particular for a control panel for a domestic appliance, comprising: a cover layer, a sensor layer which covers a rear side of the cover layer at least in sections, a display layer with at least one discrete display element, wherein the sensor layer is interposed between the cover layer and the at least one discrete display element, wherein the sensor layer is configured to detect operator inputs, in particular operator gestures, whereby the sensor layer can be activated in sections as a function of a desired input mode, and wherein the at least one discrete display element is selective User guidance can be controlled.

 Also in this way the object of the invention is completely solved.

• – Fügen der Abdeckschicht und der Sensorschicht, und
• – Zuweisen zumindest eines auszuwertenden Feldes für Bedienereingaben auf der Sensorschicht in Abhängigkeit von einer gewünschten Konfiguration des Blendenbauteils.

Concerning the manufacturing method, the object of the invention is achieved by a method for producing a diaphragm component, in particular a control panel for a household appliance, with the following steps:

• Provision of a covering layer, in particular a covering layer made of a plastics material, provision of a sensor layer that can be activated in sections, in particular a sensor layer which extends in a planar manner and which is selected to detect operator inputs, in particular operator gestures;
• - Add the cover layer and the sensor layer, and
• Assigning at least one field to be evaluated for operator inputs on the sensor layer as a function of a desired configuration of the diaphragm component.

 Also in this way the object of the invention is completely solved.

 According to the invention, the sensor layer can be arranged "invisibly" behind the cover layer for an operator, wherein the sensor layer defines an area, in particular a surface, in which operator inputs can potentially be detected. During production or operation, a section of the sensor layer can now be deliberately selected and activated in order to be able to record and evaluate user inputs there. In other words, the diaphragm component may have a basic configuration and, depending on the desired configuration, be controlled in a variant-specific manner. For example, it is conceivable to use only one or more (area) sections of the sensor layer in the selected variant actually for detecting and evaluating the operator inputs. In this way, a high variety of variants can be made at the aperture component with little effort.

 Furthermore, the activation or assignment of the sensor layer or of the selected sections of the sensor layer during operation can be effected as a function of the currently desired input mode. In other words, one and the same sensor layer or sections thereof can be selected for different inputs. In other words, in the case of a washing machine, for example, a specific selected section of the sensor layer can be used both for selecting a washing program (first input mode) and for selecting a wash temperature (second input mode). This example is merely representative of a variety of conceivable combinations and configurations for illustrative purposes.

 The sensor layer is arranged on the side facing away from the operator in the installed state of the cover layer of the diaphragm component. Accordingly, it does not lead to optical impairments if only a partial section of the sensor layer is actually used for detecting and evaluating operator inputs.

 Advantageously, according to various aspects of the present disclosure, the aperture component may be provided with a display layer (or display level) disposed behind the sensor layer (as viewed from the cover layer). In other words, the display layer and the sensor layer are arranged one above the other at least in sections. The display layer may be formed from at least one discrete display element. For the purposes of the present disclosure, a discrete display element may in particular be an optical display element which is designed to display a limited amount of information. In particular, a discrete display element is not a graphical display designed to display pixel-generated images. For the purposes of the present disclosure, a discrete display element may be, for example, status symbols, control displays, control LEDs, bar displays, segment displays and similar "discrete" display elements. Discrete display elements are usually much cheaper than pixel-based graphic display elements. Furthermore, discrete display elements regularly have a higher robustness and suitability for fluctuating environmental conditions. In other words, a large amount of information can also be displayed without a pixel-based display. The operator can be given the feeling of acting directly on the display since he can make inputs directly in the area of the activated or activatable discrete display elements.

 Thus, according to various aspects of the present disclosure, at least one discrete display element, preferably a plurality of discrete display elements defining the display layer, may be disposed "behind" the sensor layer. The at least one discrete display element can be used in conjunction with the ability to assign and activate sections of the sensor layer for selective operator guidance or operator guidance. By way of example, at least one discrete display element can be selectively activated to output an optical signal, which shows the operator that he can make inputs in the region of the activated display element, which are detected by the (hidden) sensor layer.

Preferably, the diaphragm component, in particular its sensor layer, is adapted to analog or quasi-analogue inputs of the operator capture. In other words, it is preferable if the sensor layer is not only used to switch certain functions (digital) on or off. Rather, it is possible to capture extended user inputs, in particular user gestures, which allow, for example, the selection of a value within a range of values. In this way, the operation of the household appliance can be significantly simplified. For example, within a relatively wide temperature range, the operator may select a target temperature by simply "wiping" along the cover layer. However, the operator may also, in another operating mode, make a program selection in the same area, as indicated by a corresponding activated discrete display element.

 Operator inputs may generally include an approach to the cover layer and / or a touch of the cover layer. Operator inputs can also be made on a point-by-point basis (for example in the sense of a click or a double-click). However, operator inputs may also include motion paths, such as sweeps, circular motions, or the like. Operator inputs can be made in principle with an aid, such as a pen, or by means of body parts, in particular by means of fingers or thumb. Operator inputs can also be combined to enable complex functions. This may, for example, be a zoom function, that is to say an enlargement or reduction function. By means of such complex gestures, for example, the sensitivity of the sensor layer can be influenced for specific operator inputs. Other extended / complex inputs are conceivable. By way of example, the sensitivity for wiping gestures, for example for temperature selection or time selection, can be influenced by means of a zoom gesture.

 For the purposes of the present disclosure, the term prompting may include a manual for input to the operator, but also feedback to the operator after input has been made. For example, guidance may be provided when an activated discrete display element identifies or highlights a particular area of the (hidden) sensor layer currently activated to detect operator gestures. A feedback to the operator may include, for example, a particular optical output responsive to a particular operator input. This may include, for example, changing a bar graph formed as a discrete display element. Further, the optical output may include, for example, a color change of a discrete display element. In this way, complex information can be displayed, in itself, with relatively simple display elements. There can be a sufficiently detailed user interaction, this can increase the perceived value by the operator.

 It is preferred if the cover layer of the diaphragm component completely covers the sensor layer. The covering layer is in particular a substantially closed covering layer which completely covers the sensor layer. The sensor layer is preferably arranged on the rear side of the covering layer, that is to say on the side of the covering layer which is remote from the operator during normal operation.

 The manufacturing method for producing the diaphragm component allows a great flexibility in the production. Since a large potentially activatable sensor surface can be provided by means of the sectionally activatable sensor layer, sections for user input can be selected therefrom by suitable contacting or activation (in each case according to the currently desired configuration). The introduction of the sectionally activatable sensor layer is not associated with significant additional effort. On the contrary, cost advantages in production can arise since a large number of variants can be realized on the basis of a basic configuration. The variants may differ from each other in terms of their functionality. Regardless of whether the household appliance to be produced has a low, medium or even a high level of functionality, the required operator inputs can be detected and evaluated in a simple manner by the configuration and activation of the activatable sensor layer.

 By way of example, the diaphragm component can be provided with the sensor layer in the above-mentioned manner and can be printed or otherwise treated on its side facing the operator in order to generate operator-perceivable operating symbols. On the basis of the currently selected layout of the printing or processing, a corresponding layout of the sensor layer for selective activation can now be selected by software or control technology. In other words, a control device can be designed and designed such that operator inputs are detected only in the areas of the sensor layer that correspond to the operator symbols generated on the cover layer. The corresponding assignment of the selected sections of the sensor layer can be realized in a simple manner by software or circuit technology. In other words, a freely scalable control panel can be created. The control panel can receive its functional assignment at the end of the production process.

• – Bereitstellung zumindest eines diskreten Anzeigeelements,
• – Fügen der Abdeckschicht, der Sensorschicht und des zumindest einen diskreten Anzeigeelements, wobei die Sensorschicht der Abdeckschicht und dem zumindest einen diskreten Anzeigeelements zwischengeordnet wird, und
• – Bereitstellen einer Schnittstelle für eine Steuereinrichtung zur Ansteuerung des zumindest einen diskreten Anzeigeelements und zur Auswertung von an der Sensorschicht erfassten Bedienereingaben zur selektiven Bedienerführung.

The method for producing the diaphragm component can be developed by the following steps:

• Providing at least one discrete display element,
• - Adding the cover layer, the sensor layer and the at least one discrete display element, wherein the sensor layer of the cover layer and the at least one discrete display element is interposed, and
• - Providing an interface for a control device for controlling the at least one discrete display element and for the evaluation of detected at the sensor layer operator inputs for selective operator prompting.

 The interface may be, for example, a contacting of the sensor layer via which the control device communicates with the sensor layer. Furthermore, the interface may comprise contacting the control device with the at least one discrete display element so that the control device can selectively activate or deactivate the at least one discrete display element.

• – Zuweisen zumindest eines definierten auszuwertenden Feldes für Bedienereingaben, insbesondere Bedienergesten, auf der Sensorschicht zur Definition eines aktuellen Eingabemodus in Abhängigkeit von dem gewünschten Eingabemodus.

The method may further comprise the following step:

• Assigning at least one defined field to be evaluated for operator inputs, in particular operator gestures, on the sensor layer for defining a current input mode as a function of the desired input mode.

• – Bearbeitung der Abdeckschicht insbesondere Bedruckung oder Beschichtung, zur Erzeugung zumindest eines optisch und/oder haptisch wahrnehmbaren Bediensymbols zu Bedienerführung, und
• – Zuweisen zumindest eines auszuwertenden Feldes für Bedienereingaben auf der Sensorschicht in Abhängigkeit von einer Größe und/oder Anordnung des zumindest einen optisch und/oder haptisch wahrnehmbaren Bediensymbols zur selektiven Bedienerführung.

Alternatively or additionally, the method can be developed by the following steps:

• - Processing of the cover layer, in particular printing or coating, for generating at least one optically and / or haptic perceptible operating symbol for user prompting, and
• Assigning at least one field to be evaluated for operator inputs on the sensor layer as a function of a size and / or arrangement of the at least one optically and / or haptically perceptible operating symbol for selective operator guidance.

 In other words, the operator guidance by means of selectively activatable elements, the at least one discrete display element, as well as permanently existing elements, the at least one optically and / or haptic perceptible operating symbol, take place. Both types of elements can be combined with each other in an advantageous manner.

 In a preferred embodiment of the diaphragm component, the sensor layer is designed as a capacitive sensor layer, wherein the sensor layer is designed in particular to detect touches on the cover layer and / or approaches to the cover layer in the region of the sensor layer.

 In other words, the sensor layer can be designed approximately as a projected capacitive sensor layer. The sensor layer may in particular be designed as a film-based sensor layer. It is understood that other functional principles for the sensor layer can be used to detect touches and / or approaches to the cover layer. By way of example, the sensor layer can be configured as an inductive sensor layer, a resistive sensor layer, as an optical sensor layer and / or as a combined sensor layer.

 The sensor layer may in particular comprise two mutually insulated planes, which are each provided with conductive material. By way of example, a first level may have a row structure and a second level a column structure. Other designs such as diamonds or the like are conceivable. It is particularly preferred if the sensor layer is designed to detect multi-dimensional operator gestures and / or multiple operator inputs simultaneously. Multi-dimensional operator gestures may include, for example, wiping motions. The ability to capture multiple operator inputs simultaneously may be referred to as multi-touch capability.

 It is further preferred if the diaphragm component comprises an interface for a control device which is designed to selectively control the sensor layer and the at least one discrete display element in order to define a plurality of input modes. The at least one discrete display element may be selectively activated to indicate to an operator that a particular type of input may be made to a particular location of the sensor layer. Via the interface, the control device can selectively activate a section of the sensor layer for inputs and evaluate accordingly.

 According to a further embodiment of the diaphragm component, the control device is designed to define a current input mode, wherein the control device is further configured to assign at least one field to be evaluated for operator inputs on the sensor layer, taking into account at least one selected input mode. This may advantageously be accompanied by the activation of at least one discrete display element to indicate to the operator where to make his input and what type of input is currently required.

In other words, it may be advantageous to form a system for detecting operator inputs, which comprises at least one diaphragm component and at least one control device according to one of the aforementioned aspects. Such a system can be formed on the one hand as a discrete component. On the other hand, it is conceivable to outsource the control function for controlling the diaphragm component to a (higher-level) control device of the household appliance. Accordingly, the system can be formed during assembly by joining the shutter member for completing the home appliance.

 According to a further embodiment of the diaphragm component, the indicator layer comprises at least one display element which is designed as a discrete, selectively activatable symbol or as a discrete, selectively activatable segment display, in particular as a seven-segment display. A selectively activatable symbol may be, for example, a light emitting diode or a collection of light emitting diodes. The selectively activatable icon may further include a symbol representation, such as a silhouette or icon illuminatable by an LED or similar light source. A selectively activatable segment display may include, for example, a bar display, a pie segment display, a multi-segment display to display alphanumeric information, or the like. Advantageously, different types of displays can be combined with each other to form the at least one display element. The at least one display element can in particular be adapted to an expected user input. For example, a wiping function can be combined with a bar segment display and / or an alphanumeric segment display. By wiping along the currently activated portion of the sensor layer, the operator can influence the immediately displayed value, so that a direct feedback is given to the operator. The at least one display element can also illustrate a limitation of the currently defined field.

 According to various embodiments, it is further preferred if the cover layer and the sensor layer are at least partially transparent or translucent. In other words, the cover layer and the sensor layer can be optically transparent at least in sections, and thus improve the optical perception of the at least one discrete display element, which can be concealed by both the sensor layer and the cover layer. The cover layer and the sensor layer may be designed to be at least partially transparent or translucent, so that, for example, when a discrete display element is not activated, this is imperceptible to the operator. In this way, the operation of the household appliance can be further simplified because currently not needed discrete display elements can be made "invisible".

 According to a further embodiment of the panel component, the cover layer is surface-treated at least in sections, in particular printed or coated, wherein the cover layer has at least one operator-visible and / or tactile operator symbol for user guidance. By way of example, the cover layer can be printed. Alternatively or additionally, the cover layer may be provided with raised or recessed shape elements. Furthermore, it is conceivable to influence the surface condition of the cover layer in a targeted manner in order to clearly highlight the at least one operating symbol. The measures mentioned can be combined with each other.

 In this way, as an alternative or in addition to the selectively activatable discrete display elements, the diaphragm component can be provided with permanently visible elements in order to identify input possibilities for the operator. The at least one optically and / or haptically perceptible operating symbol may comprise, for example, a graphical representation and / or an alphanumeric representation. In particular, the use of pictograms is conceivable. The at least one operating symbol of the covering layer can be associated with the sensor layer, a corresponding field or a section in which user inputs that are linked to the operating icon, can be detected.

 It is particularly preferred if an aperture component according to one of the aforementioned aspects is used in a domestic appliance.

• – Aktivieren zumindest eines diskreten Anzeigeelements einer Anzeigeschicht, die auf der der Abdeckschicht abgewandten Seite der Sensorschicht angeordnet ist, zur Kennzeichnung des auszuwertenden Feldes der Sensorschicht.

The method for selective prompting can be further formed by the following step:

• Activating at least one discrete display element of a display layer, which is arranged on the side of the sensor layer facing away from the cover layer, for identifying the field of the sensor layer to be evaluated.

 It is particularly preferred if the defined field to be evaluated is at least adjacent to the activated discrete display element. In particular, it is preferred if the assigned field to be evaluated (from the perspective of the operator) is located in front of the activated discrete display element. In this way, it may give the operator the impression of being able to make the desired inputs directly at the display element, such as a selection or a change of a value.

According to a further advantageous embodiment of the method for operator guidance, the step of defining the current input mode further comprises the step of assigning the field to be evaluated for operator inputs to an operating symbol that is visually and / or haptically perceptible on the cover layer. In this way, permanently perceptible symbols can be used to guide and guide the operator. Preferably permanently visible elements and selectively activatable elements can be combined with each other in order to further increase operator comfort and reduce the risk of incorrect operation. It is further preferred to extend the method for selective operator guidance by the step of outputting a feedback to the operator, in particular a visual feedback, by selectively activating at least one discrete display element of the display layer. The activation of the at least one discrete display element may also include, for example, changing the at least one discrete display element. This may include, for example, a color change. Further, this may also include changing a discrete bar graph or segment display.

 It is particularly preferred if the discrete display element activated for the purpose of feedback to the operator is in the currently assigned field or at least in the vicinity of the currently assigned field from the operator's point of view, so that the impression of direct feedback results. This can further increase the perceived value of the home appliance and the operation.

 It is understood that the features of the invention to be explained below and those to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

 Further features and advantages of the invention will become apparent from the following description of several preferred embodiments with reference to the drawings. Show it:

1 shows a perspective view of a household appliance 10 containing a shutter assembly or control panel 12 having. In the household appliance 10 it can be about a dishwasher or something similar. domestic appliances 10 For example, washing machines, refrigerators, freezers, ovens, stoves, microwaves, tumble dryers, or the like may be exemplified. There are also home appliances conceivable that combine various functions, such as fridge-freezer combinations.

By way of example, the control panel 12 at least one aperture component 14 on. The at least one aperture component 14 may include areas in which elements for operation or user interaction are arranged. It is understood that the control panel 12 in particular may be designed substantially in one piece. The orifice components 14 can be integral parts of the control panel 12 be. However, it is also conceivable, a plurality of diaphragm components 14 as single parts and into the control panel 12 to add.

2 shows a highly simplified schematic exploded perspective view of an exemplary embodiment of a diaphragm component 14 , One with 16 designated arrow indicates a typical line of sight of an operator who on the panel component 14 Operator inputs can make. On its side facing the operator, the aperture component 14 a cover layer 20 on, which can be designed in particular as a plastic component. From the perspective of the operator "behind" or "below" the cover layer 20 is a sensor layer 22 arranged. The sensor layer 22 can be used as a sensor layer 22 be designed to detect touches or approximations. It is understood that the sensor layer 22 in the basis of the 2 illustrated embodiment may be formed to touch or approximations at the level of the cover layer 20 to capture the sensor layer 22 can cover, in particular completely cover. The sensor layer 22 In particular, it can be configured as a conductive foil which is sensitive to contact at least in sections.

To the sensor layer 22 may be rückwertig, ie on the side facing away from the operator in normal operation of the diaphragm component 14 a so-called display layer 24 connect. This can be configured, for example, to certain areas of the sensor layer 22 to visually highlight to the operator for purposes of operator guidance and interaction. According to various exemplary embodiments, the cover layer 20 at least partially with transparent or translucent areas 26 be provided. Similarly, the sensor layer can 22 be at least partially translucent or transparent.

This sensor layer 22 can be a sensor network 28 and be designed approximately as a film component having different conductive areas. The sensor layer 22 may be designed as a transparent film, but alternatively also as a substantially opaque or opaque film. It is understood that the sensor layer 22 may comprise a layer structure, for example, different conductive layers isolated from each other. The sensor layer 22 may generally define a range in which operator inputs (touches or approximations) in the area of the cover layer 20 recorded and evaluated.

The display layer (also: display level) 24 can be at least a discrete display element 30 include. By way of example, the reference to the 2 illustrated display layer 24 a first discrete display element 30a and a second discrete display element 30b , The display layer 24 does not have to be provided as a physical part. Rather, the display layer 24 at least in some embodiments as a (logical) summary of various discrete display elements 30 be understood. It is understood, however, that in alternative embodiments, the display layer 24 exemplified as a support structure for the at least one discrete display element 30 can act.

The at least one discrete display element 30 may be exemplified as a pictogram, icon, (pre-defined) alphanumeric display, segment display, segmented bar graph, or the like. The at least one discrete display element 30 in particular, should not be understood as a pixel-based graphic display element. Rather, it is preferred if the at least one discrete display element is predefined and designed to display exactly one graphical information or a limited number of different graphical information. The at least one discrete display element can in particular be illuminable in order to ensure sufficient visual emphasis for the operator. Light-emitting diodes, (discrete) LCD elements or the like are suitable for this purpose. A limited variation of the at least one discrete display element 30 representable information can be done for example by color highlighting. Furthermore, in particular with segment-type discrete display elements 30 by controlling different segments / sub-elements, a variation of the representable information. Accordingly, by means of segment displays, alphanumeric information can also be displayed, at least to a limited extent, whereby the number of displayable characters or letters is predefined and limited.

shutter members 14 According to various embodiments of the present disclosure, use is made of the sensor layer 22 large area at a reasonable cost on the cover layer 20 can be applied. A joining of the cover layer 20 with the sensor layer 22 may include, for example, gluing, encapsulation, injection molding, embedding, a non-positive and / or positive mounting and other common joining methods. In this way, the aperture component 14 in a basic configuration, such as the cover layer 20 as well as the sensor layer 22 , be manufactured at reasonable cost in mass production. The iris component 14 is particularly suitable for selective packaging. This can be about assigning sections or fields sensor layer 22 to capture specific operator input. In other words, a predefined basic configuration can be used by targeted control of the sensor layer with little effort for a large number of variations with regard to the permitted and offered operating scopes.

Based on 3 and 4 , each greatly simplified schematic sections through aperture components 14 show exemplary embodiments in terms of the layer structure of the diaphragm components 14 illustrated. 3 shows an aperture component 14 , which is essentially based on the 2 illustrated aperture component 14 can correspond. The iris component 14 according to 3 has a cover layer 20 , a sensor layer 22 and a display layer 24 on. The display layer 24 is with different discrete display elements 30a . 30b . 30c Mistake. The iris component 14 is with a control device 42 can be coupled via an interface 36 and corresponding connection cables 38 . 40 with the sensor layer 22 and the display layer 24 can communicate. The control device 42 is over the connecting line 38 with the sensor layer 22 connected. About the connection line 38 can the controller 42 Capture information about touches or approaches to an exterior surface 34 the cover layer 20 describe. Operator inputs can be made by means of an actuator 32 . 32a be made. At the actor 32 . 32a it may in particular be a body part of the operator, such as a finger. However, it is also conceivable to use a stylus or the like. The sensor layer 22 and the controller 42 may be configured to touch the cover layer 20 to capture, cf. the finger 32 , Alternatively or additionally, the sensor layer 22 and the control device 42 also be designed to approximations, so no direct contact with the cover layer 20 to capture, cf. the finger 32a ,

The control device 42 can also via the connecting cable 40 with the discrete display elements 30a . 30b . 30c be coupled. The discrete display elements 30a . 30b . 30c can be selectively activated or activated to guide the operator or to guide at a desired operator input. In particular, the discrete display elements 30a . 30b . 30c for visually highlighting a currently assigned and provided subsection or field from the sensor layer 22 be used. In this way, the sensor layer 22 be used for a variety of inputs and is flexibly configurable in this regard.

It is understood that the discrete display elements 30a . 30b . 30c in various alternative embodiments can also overlap at least partially. In this way, one and the same area of the cover layer 20 depending on the configuration of the sensor layer 22 be used for various inputs. By way of example, one and the same area can be used in a washing machine to select a program mode, for temperature preselection and for the time control and for the associated required user inputs or operator inputs. It goes without saying that the section actually used or the respectively selected field of the sensor layer 22 not identical or congruent. Rather, by logical control of the sensor layer 22 a plurality of sections or fields defined and used for the detection and evaluation of operator inputs. The definition and assignment of the fields can take place, for example, in terms of software and / or circuitry.

For the control or evaluation of at the sensor layer 22 detected inputs is the aperture component 14a with a control device 42 coupled by means of a connecting cable 38 via an interface 36 with the sensor layer 22 is connectable. The cover layer 20 can also with at least one control symbol 46 be provided. By way of example, this is indicated by the 4 illustrated aperture component 14 on its cover layer 20 a raised control symbol 46a and a sunken operator symbol 46b on. In general, the operating icons 46 visually and / or haptically perceptible in the cover layer 20 be provided.

Within this potentially possible area can now be about fields 60a . 60b be defined, the subsets of the sensor layer 22 can represent. The assignment and definition of the fields 60a . 60b can be flexible and associated with a low (software or circuit-related) effort. One and the same area of the sensor layer 22 can (time spaced) for different fields 60 be used, which can overlap at least partially. For local registration of operator input, in the field 60a are made in particular with 62a . 64a designated areas of the sensor layer 22 evaluate.

The areas 60a . 60b are flexibly selectable and can be software-like or circuit-wise in the control device during production, for example 42 (see. 3 and 4 ) are deposited.

Based on 7 . 8th . 9 and 10 Illustrated are various other exemplary embodiments of panel components having various discrete display elements and / or operator control icons.

The iris component 14b according to 7 assigns information objects 68a . 68b basically, by one of the display elements 30 the display layer 24 or by one of the operating icons 46 the cover layer 20 can be formed. Furthermore, the aperture component 14b discrete display elements in the form of pictograms 70a . 70b on. At the pictograms 70a . 70b For example, these may be illuminated displays or illuminated symbols. In the present configuration, fields 60a . 60b the sensor layer 22 (see. 6 ) are defined or selected such that a first field 60a extends in an area where the pictogram 60a is arranged. Furthermore, a field may be 60b extend in an area where the pictogram 70b is arranged. The operator can now input directly over the pictograms 70a . 70b Furthermore, they can also show him the desired type of input.

By way of example, the operator in the field 60a make a swipe or sliding movement, which is indicated by the pictogram 70a oriented, which represents a double arrow. In this way, the Select operator about a temperature. The pictogram 70b illustrates a circular arrow. In this way, the operator can be indicated that he can choose about a program by means of a swipe movement along a circular path about. That on the basis of 7 The illustrated embodiment may be coupled to another display (not shown) to provide feedback to the operator regarding his input.

8th illustrates another exemplary embodiment of a diaphragm component 14c , The iris component 14c is exemplary with information objects 68a . 68b provided, which may be configured as printed or similarly designed control symbols. Furthermore, the aperture component 14c Display elements in the form of segment displays 72a . 72b on, which (logically) with defined fields 60a . 60b the sensor layer 22 (see. 6 ) are linked. Each of the segment displays 72a . 72b may consist of a plurality of selectively activatable segments 74a . 74b be formed. The segment displays 72a . 72b and the fields associated with them 60a . 60b can be linked together so that a user can make an input directly on the respective display. In other words, the operator may be about one of the segments 74a . 74b activate by appropriate touch or a similar gesture. A response to the operator can be made without significant delay by activating or deactivating the corresponding segment 74a . 74b respectively.

The segment display 72a can act as a bar graph. The bar graph can illustrate about a temperature level. By touching or "wiping", the operator can select a desired temperature level which is immediately available to him by a corresponding activation of the segments 74a the segment display 72a is returned. Similarly, the operator at the segment display 72b by choosing one of the segments 74b choose a desired program. This can be done immediately after his election by visually highlighting the chosen or deselected segment 74b be illustrated.

9 shows a further alternative embodiment of a diaphragm component 14d , Also the aperture component 14d may have operating symbols that on the associated cover layer (see. 4 ) are visually and / or haptically perceptible. This can be about a print 68 act. The printing 68 can be an example of a linked field 60b which is in the area of a pictogram, for example as a light symbol 72 is designed. Together, the printing can 68 and the light symbol 70 guide the operator in his input. It is understood that a selected (control) field 60 Basically, only with a passive control icon, such as a passive printing or the like can be linked without the (control) field 60 an (active) display element is assigned. A corresponding printing may include, for example, a symbol as well as an identification of the area in which the user can make his input or make his selection.

Furthermore, the aperture component 14d a segment display 76 which is designed in particular as a 7-segment display. The segment display 76 has a plurality of segments 78 on. The 7-segment display 76 is a corresponding field 60a assigned for operator input. So it is conceivable that the operator in the field 60a Entries directly on the display 76 by selectively activating or deactivating one of the segments 78 , It is also conceivable that the segment display 76 is used for feedback to the operator when this is about in the field 60b Entries above the pictogram 70 performs.

10 illustrates a further embodiment of a diaphragm component 14e , which may have various display elements and operator control icons. For example, an operating symbol is in the form of a print 68 , representing a clock, provided. In this way, the operator is informed that the aperture component 14e a time period or time is adjustable. This can be done, for example, in a field 60b done in the sensor layer 22 is defined. The field 60b can be an example of a 7-segment display 76 be assigned. The field 60b can also have a pictogram or light icon 70b cover, where the operator can make his inputs. A feedback can be made directly via the 7-segment display 76 respectively.

The iris component 14e also has a field 60a on, that over a pictogram 70a is arranged. The pictogram 70a can show the operator as an example that he is in the field 60a Input to scale or adjust the input sensitivity in the field 60b make. In other words, the operator can work in the field 60a use a "zoom gesture" to decrease or increase the sensitivity for time inputs. In this way, on the one hand, a rapid passage through the possible value range can be made possible. On the other hand, where it is desired, a highly accurate input can be made. It would also be conceivable in principle, an input field 60c Immediately above the symbol to arrange, by the printing and / or surface treatment 68 is illustrated. In this way, a user can, for example, by gestures, which he directly on the symbol (here about on the Presentation of a clock) makes a corresponding input.

It is understood that the active objects 70 . 72 and 76 , based on the 7 to 10 be illustrated as display elements in the display layer 24 can be arranged. These elements can be selectively activated and thus visually through the sensor layer 22 and the cover layer 20 through the operator.

It is further understood that the basis of the in the 7 to 10 Aspects and embodiments illustrated in any of the examples shown configurations can be combined in any way with each other in order to provide the user in a simple manner with a small manufacturing cost, a variety of different input options. This basically takes place with a high number of variants. A significant advantage is the free scalability and assignability of the selected (operating) fields 60 in the area passing through the sensor layer 22 is basically provided.

11 illustrates in a simplified manner an embodiment of a method for operator guidance, such as for operator inputs in a household appliance. This can be done advantageously with a diaphragm component 14 and a control panel provided therewith 12 carried out according to various of the above-mentioned and described aspects. In a step S10, a diaphragm component is provided which comprises a sensor layer concealed by a cover layer and designed to detect operator inputs and, in particular, operator gestures.

 In a further downstream step, a current input mode is defined. In particular, step S12 may include a (partial) step S14 in which a field comprising approximately a portion or a subset of the sensor layer is defined and assigned for evaluation. This may be further linked to a (partial) step S16, which comprises activating at least one discrete display element to visually illustrate to the operator the currently activated field for its inputs. Alternatively or additionally, a (partial) step S18 may be provided in step S12, which comprises the assignment of a selected (operating) field to an operating symbol provided on the cover layer of the panel component. The operator icon may be a printed operator icon or the like. The operating symbol can be assigned (in terms of software or circuitry) a field which can basically be freely selected in the area of the sensor layer.

 The step S12 may further include an optional (sub-) step S20 including an output of a feedback to the operator. For this purpose, at least one discrete display element can be activated or activated. In this way, the operator's input can be immediately visually identified. In particular, it is preferred if the at least one display element is arranged in the region of the currently assigned field for operator inputs. This may give the operator the impression of making his inputs "directly" on the display element. The step S12 may be followed by a step S22, which comprises the detection and evaluation of the operator inputs in the currently defined field to be evaluated.

12 illustrated in a simplified manner an embodiment of a method for producing or producing a diaphragm component, in particular for a control panel of a household appliance. The method may include steps S30, S32 and S34. The step S30 comprises the provision of a cover layer, in particular a cover layer of a plastic material. Step S32 comprises the provision of a sensor layer that can be activated in sections, in particular a sensor layer that extends in a planar manner and that is designed to detect operator inputs, in particular operator gestures. Step S34 includes providing a display layer that includes at least one discrete display element that is selectively activatable.

 The steps S30, S32 and S34 may be followed by a step S36, which includes the joining of the cover layer, the sensor layer and the display layer. In this case, the sensor layer can be arranged on a (in normal operation) the operator facing away from the cover layer. On the side of the sensor layer facing away from the operator, the display layer can be arranged with the at least one discrete display element.

It may be followed by a step S38, which comprises an assignment of at least one defined field on the sensor layer in dependence on a desired input mode. By way of example, fields on the sensor layer 22 be selected and defined, which are associated with at least one discrete display element. Furthermore, however, fields can also be selected which are associated with operating symbols or similar optically and / or haptically perceptible symbols which are provided in the covering layer. The step S38 can be particularly flexible in order to realize a multiplicity of variants on the basis of a given sensor layer.

The step S38 may include a step S40, which comprises providing an interface for driving the sensor layer and, if necessary, for controlling the at least one discrete display element. Further, step S38 may include providing and setting up a controller as illustrated by step S42. A control unit can be linked via the interface with the composite of cover layer, sensor layer and, if present, display layer. In step S38, a database or database can be used, cf. the reference symbol S44. A plurality of potentially possible configurations including respective input modes can be stored in the database. Using the database, in step S38, a flexible assignment and configuration of a system can take place, which includes the diaphragm component as well as the control device or the associated control device linked thereto via the interface. A configuration of the control device can be done by software and / or hardware.

 Overall, the sensor layer, which is provided areally in the cover layer, allows a free and flexible configuration for a large number of different operator inputs. The sensor layer, if present, can be used for user guidance and interaction with the user / operator. The operator can also be offered with comparably simple discrete display elements or provided on the cover operating icons the ability to make complex operator inputs. This can be done in particular without expensive pixel-based display elements, so that the production can be done with reduced effort.
